Provided is a compact dipole antenna for a radio frequency identification (RFID) tag. The antenna includes a substrate, a dipole radiator including a first dipole element and a second dipole element, in each of which a first meander line formed in a meandering shape and an arm configured of a triangular pattern which is an end connected to the first meander line, are arranged to face each other, wherein the first and second dipole elements are arranged on the substrate to be perpendicular to each other, and an impedance matcher, which includes a second meander line formed in a meandering shape, is formed at a point at which the first and second dipole elements are perpendicular to each other, and performs an impedance matching between the antenna and an RFID tag chip through the second meander line.


A method of manufacturing a thin film according to an exemplary embodiment of the present invention includes preparing an ink in which nickel oxide nanoparticles are uniformly dispersed, coating the ink on a base layer, and curing the ink to form a thin film including nickel oxide nanoparticles.


Provided are a pharmaceutical composition for preventing or treating neurodegenerative diseases including an agent capable of suppressing expression or activity of SHP-1/-2 or FcRIIB, a method of preventing or treating neurodegenerative diseases by administering the pharmaceutical composition, a method of screening for a therapeutic agent for neurodegenerative diseases, a diagnostic composition for neurodegenerative diseases, a diagnostic kit for neurodegenerative diseases including the diagnostic composition, and a method of providing information for the diagnosis of neurodegenerative diseases by using the diagnostic composition or kit. The agent capable of suppressing expression or activity of SHP-1/-2 or FcRIIB according to the present invention inhibits signal transduction caused by propagation of -synuclein to neighboring cells, thereby reducing cytotoxicity of -synuclein to neighboring cells and thus being usefully applied to a therapeutic agent for neurodegenerative diseases. Furthermore, the agent capable of suppressing expression or activity of SHP-1/-2 or FcRIIB according to the present invention may be an important clue to elucidate the pathogenesis of neurodegenerative diseases, and therefore, contributes to fundamental cure, thereby overcoming neurodegenerative diseases.
